The IMM-Rome has been derived by a former Research Unit called Project Sensors and Microsystems (CNR-PSM). Such a project officially begun on October 23, 1997. Personnel and Equipments were partially relocated from the former Institute for Solid State Electronics of CNR (now IFN). The development of technologies and devices in the new area of the micro-electromechanical systems (MEMS), and the industrial oriented approach in solving problems for the short and medium term were the main aspects of this pioneering research management experiment. After the full re-organization of the CNR, the CNR-PSM was promoted to be a permanent structure, as a section of a new Institute which collects scientists and technologists from Microelectronics, Microsystems and Sensors areas.
